    • A moving particle display device comprises an array of display cells, each cell comprising an enclosed volume containing display particles. The display cells are the disposed between the first and second electrode arrangements, and the particles are provided for movement between a first region adjacent the first electrode arrangement and a second region adjacent the second electrode arrangement. Each cell is associated with a group of electrodes (60,62,63) used to control the particle movement within the cell, wherein for most of the cells, the group of electrodes is arranged to provide asymmetry in the electric field lines (140) in the enclosed volume, thereby to influence the particle flow conditions within the display cell.

    • The invention relates to an electrophoretic device comprising one or more cells. Each of the one or more cells of the device comprises a bottom substrate having a bottom substrate area (110), a top substrate (120) having a top substrate area, and a spacer structure (130) spacing apart the bottom and top substrates to form a space containing a suspension of particles (140) in a medium, the particles being movable through application of an electric field. The bottom substrate comprises a bottom electrode having an effective bottom electrode area, and the top substrate comprises one or more independently- addressable top electrodes (121, 122) having an effective top electrode area. The bottom and top electrodes are arranged to establish the electric field, and to control a distribution of the particles from a distributed state to a collected state. The effective top electrode area is in the form of a pattern. The ratio of the effective bottom electrode area to the effective top electrode area is larger than one, and the ratio of the top substrate area to the effective top electrode area is larger than or equal to 5. The electrophoretic device of the invention has built-in grey scales, an improved manuf acturability through a relatively simple electrode arrangement, and allows the formation of a transparent state.
